Changelog for Teamscale 6.3

Newer Release Available

Our current release is available here


Check out the Release Newsletter for Teamscale 6.3.

Changed permissions when running Teamscale in Docker

  • New: As of Teamscale 6.3, Teamscale is no longer executed as the root user in the Docker container, but as user teamscale (UID=1000). Please make sure to either allow this user to access the mounted directories and files or add a user mapping to your docker-compose file, e.g. user: technical-user, which refers to a user whose permissions should be mapped to teamscale.

Versions older than 4.0.0 are no longer supported

  • New: As of Teamscale 6.3, importing data from versions earlier than 4.0.0 is no longer supported

Changed System Requirements

  • As of Teamscale 6.2, running the Teamscale server requires a Java Runtime Environment, Version 11 or later.

Deprecated REST XML Interface

  • As of Teamscale 6.0, Teamscale's REST XML interface has been deprecated. Accordingly, any existing scripts should be migrated to the new public API.

Changed loading of configuration files and locating relative paths

  • As of Teamscale 6.0, all configuration files are loaded using the same logic. In particular configuration files in the process working directory take precedence over ones in the Teamscale installation.
  • Relative paths specified in configuration files will always be resolved to the working directory. The working directory usually equals the installation directory unless explicitly changed.
  • Custom check JAR files can be deployed in a directory relative to the working directory and installation directory.
  • Searching for a Teamscale configuration file in the installation root directory. Use the file in one of the config directories.
  • Searching for a license in the installation root directory or a directory specified by the Java system property teamscale.license.path is no longer supported. Use the environment variable TEAMSCALE_CONFIG to specify a separate configuration directory or pass the license using the TS_LICENSE environment variable if you cannot place the license in one of the config directories.
  • The administrative service to read and write configuration files via the Web API (config-files) has been removed.

Update from Older Version

  • When updating from 6.3.x, drop-in.
  • When updating from 6.2.x or earlier, a full re-analysis via backup is required.
